Describe in Detail
The diagram shows a square of side 8 cm and four congruent triangles of height 7 cm.
(i) The area of one triangular face
(ii) The area of the whole shape
(b) What is this shape, which is a net of a solid?
(a) (i) The area of triangle: , where, h = height and b = base.
So, here, height h = 7 cm and base will be the side of square so base b = 8 cm
So, area of one triangular face =
(ii) The area of whole shape =
So, area of square =
So, area of whole shape =
(b) The shape is the net of a solid. So, it is called as Square Pyramid.
- If there are all equilateral triangles then the pyramid is called as Johnson Solid.
